Embodiment Construction
[0018] As shown in the figure: the untwisting pipe body 1 is provided with a cylindrical cavity untwisting chamber 2, and the untwisting pipe body 1 is provided with an air injection hole 3 penetrating through its wall. The center line of the twist chamber 2 intersects at an acute angle in different planes, that is, the center line of the air injection hole 3 and the center line of the untwisting chamber 2 respectively belong to two planes, but their projection lines intersect at an acute angle, and the air injection hole 3 The spraying direction is set eccentrically with the center line of the untwisting chamber 2, and an installation part is provided on the untwisting pipe body 1, and a carding strip protruding into the untwisting chamber 2 is provided on the inner wall surface of the untwisting pipe body 1. 4. There are several jagged protrusions 5 on the carding bar 4 .
[0019] The air injection hole 3 is a cylindrical revolving body cavity, and a generatrix of the air in...

The invention relates to a spinner fitting, in particular to a metal detwisted tube used in a rotational air splicer with teeth. According to the technical proposal of the invention, a detwisted cavity body with a cylindrical hollow cavity is arranged in the body of the detwisted tube, a fumarole that runs through the wall body of the detwisted tube is arranged on the body thereof, a centerline of the fumarole is intersected with a bifacial acute angle of the centerline of the detwisted cavity body, the ejection direction of the fumarole and the centerline of the detwisted cavity body are arranged eccentrically, an installation part is arranged on the detwisted tube body, carding strips that extrude into the detwisted cavity body are arranged on an inner wall of the detwisted tube body and a plurality of tooth-shaped convexes are arranged on the carding strips. The invention realizes uniform untwisting of yarn or thread odds in the detwisted cavity in actual use based on hydrokineticsprinciple and adapts to untwisting requirements of different types of yarns, besides, the detwisted tube is made of metal material, thereby having reasonable structure and design, long service life and stable, uniform and reliable yarn untwisting.
Description
technical field [0001] The invention relates to a spinning machine accessory, in particular to a metal untwisting tube for a swirl untwisting air splicer with sawtooth. Background technique [0002] The air splicer for textile is an important equipment for producing jointless yarn in the textile industry. The swirling untwisting air splicer is mainly composed of air system, swirling untwisting system and twisting system. [0003] In the prior art, the rotating air flow untwisting mechanism mainly adopts a metal untwisting tube with a central through hole, and an eccentric and downwardly inclined air jet hole opposite to the twist direction of the yarn is opened on the upper part of the untwisting tube. It rotates at a high speed in the through hole in the center of the untwisting tube, so that the yarn and thread tail are sucked by the swirling flow to realize untwisting. The loss and untwisting tube adopts a single small air jet hole, which causes defects such as unstable...
